Motor Control of Hand Force for Visual Indicator Without Hand Displacement

This study assessed the hand force exerted to a fixed controlled object under three conditions with the dominant and non-dominant hand. The position, velocity, and acceleration of a visual indicator were determined by the exerted hand force and the participants were asked to move the indicator to a target position. Our findings indicated that the non-dominant hand had an advantage when an appropriate magnitude and time interval was required while the dominant hand had an advantage in the pseudo-natural condition. These findings could be applied to the designing of devices and interfaces.
